RESUMEN
A male patient in his 50s presented to the emergency department with a three-day history of shortness of breath, New York Heart Association class IV, and oxygen desaturation. His physical examination revealed a large volume radial pulse with bibasal crepitation in the lungs and a soft diastolic murmur in the aortic area on auscultation of his heart. He was managed on the line of decompensated heart failure. Transthoracic echocardiography showed a dissection flap in the ascending aorta with acute severe aortic regurgitation. A subsequent urgent CT angiography of the whole aorta confirmed a complex type A aortic dissection with an aneurysmal ascending aorta. An emergency type A aortic dissection repair (modified Bentall's procedure) was done. The patient made a good recovery, was discharged successfully 2 weeks after the procedure and was doing well on postoperative follow-up.
